I believe there are thousands of different reasons a woman might want to have an abortion. They can have opinions coming left and right and of course their families and the father of the child have an opinion, but when it comes down to it, she should have that right.
Nearly 90% of abortions are performed before 12 weeks, and over 95% done in the first 20 weeks. This means that most are done in the first trimester while a very low percentage that are done after roughly 5 months. As far as I know third term abortions are absolutely not performed unless there is serious danger to the baby and/or mother. Brain wave activity is apparent at about the 6th week but it is not fully developed. Fetal stage begins at roughly 8 weeks. Most abortions occur before the babies brain, and vital organs have come close fully developing, and the baby could not live outside of the womb until around the 25th-28th week of pregnancy. Which again, means most abortions would occur over a month prior to this time. I appologize if I offend, but I don't consider a child to be a life until around this point. I consider it to be a potential life. I wouldn't agree for any third trimester abortion unless it was for serious medical reasons, and late second is really pushing it.
I personally have no idea what I would do were I to get pregnant at this very moment in time. In all honesty, I would probably have the child. However, I still feel that I have the right to terminate the pregnancy if I so choose. As I believe every other woman should.
